Hello all,

I am venturing into the wide world of Ruby and IronRuby. I have the  
IronRuby source code setup and building thanks to Ben H. and some  
clarifications from this forum. I am building via Visual Studio.  
Currently, I am able to do some .Net interop. Right now, I am a little  
confused on how or if Ruby interacts with IronRuby. Do I need to  
install Ruby in a specific location? Are there any settings I need to  
set? And if so which ones and where? And finally, I want to verify  
whether there are issues with Windows Ruby and Ruby install via cygwin?

Thanks,

Tim

Tim,

IronRuby itself is (or will be) a complete ruby implementation. You do  
not  
need to have CRuby installed. You can use an existing ruby installation  
to  
build IronRuby using rake, as you are building via Visual Studio you do  
not  
require this.

As for the last part, I’m not sure what issues you are referring to, I  
do  
most of my day to day ruby via cygwin, I also have win32 Ruby (via the  
one-click installer) for testing the rakefile for IronRuby…

Thanks for the response. I was refering to the following post:

[http://blog.mmediasys.com/2008/10/27/handy-tip-dont-mix-one-click-installer-with-cygwin/](http://blog.mmediasys.com/2008/10/27/handy-tip-dont-mix-one-click-installer-with-cygwin/)

Also, I am using the e-text editor, which uses cygwin ruby, and when I  
install the one click, I get ruby load errors when running cygwin ruby.

You can run both, the issue can occur when GEM\_HOME points to the others  
directory, i.e. you’re in cygwin and GEM\_HOME points to the one click  
installer’s gem repository.
